TIRE CHAN.

Maaate.

Application filed August 30, 1921.

To all iii/0m t 7720.7/ concern Be it known that l, Louis G. S'rUnnNone, a citizen of the UnitedStates ot America, residing at Memphis, in the county oi Shelby and `State ot Tennessee, have invented new and useful improvements in Tire Chains, ot which the following is a speciiication.

T his invention comprehends the provision o1 an. anti-skid attachment tor automobile wheels or the like, in the nature of a chain adapted to extend across the tread oit'the tire with its ends associated with the spokes oit the wheel tor holding the chain in proper position tor use.

rlfhe chief characteristic of the present invention resides in equipping the chain with a pair ot springs, each spring being terminally connected with the chain at spaced points to provide a slack in the chain when the wheel is not in motion, the springs being positioned to gradually take up any undue strain or pull to which the chain might be subjected to, incident to tast driving or turning` corners, thus preventing` the chain trom being broken by sudden jerks or pulls thereon.

The nature and advantages of the invention will be better understood when the tollowing detailed description is read in connection with the accompanying drawings, the invention residing inthe construction, combination and arrangement of parts as claimed.

ln the drawings forming part of this application. like numerals ot reference designate similar parts in the several views, and wherein Figure 1 is a fragmentary side elevation ot an automobile wheel showing one oi the tire chains associated therewith.

Figure 2 is an enlarged transverse sectional view showing the normal position of onechain and its spring.

Figure 3 is a view similar to Figure 'l showing the arrangement of the springs when the chain is subjected to undue strain or pull.

Figure t is a plan view ot one 'ot the chains.

Referring to the drawings, in detail, 10 designates an automobile wheel ot the usual construction`r while 11 represents the usual pneumatic tire. The attachment forming the subject matter of the present invention comprises a chain 12, trom one end ot which extend the branches 13. This chain is of Specification of Letters Patent.

j Patented Jnft 18, sei-iai no. 496,811.

a length to extend about the tire and the telly ot the wheel as clearly illustrated in Figure 2. The branches 18 are adapted to surround the adjacent spoke of the wheel, and these branches are secured together through the instrumentality of a snap hook 14. sleeve 15 ot rubber or other suitable material surrounds each branch 13 ot the chain to prevent the spoke from bein scratched or otherwise marred as will be readily understood.

l ith each chain, l make use ot a pair ot springs 17, and each spring has its end secured to the chain at spaced. points, in a manner to provide tor a slackness indicated at 1S when the wheel is not in motion. When the chain is positioned upon the wheel, these springs 17 are arranged at opposite sides ot the tread ot the tire, and in their normal condition provide for a slackness as clearly shown in Figure 2. `When the machine is tavelling at a reasonably fast rate ot speed, there is considerable pull exerted upon each chain, which pull is gradually taken up by the springs before the pull is transmitted to the chain, thus preserving the chain trom breakage which would obviously result should the chain be subjected to any sudden jerk or pull ot an aggravated nature. When the springs 17 are used in the manner as stated, the springs are extended as illustrated in Figure 3, and these springs are eXtened to approximately their limit before the slack in the chain is taken up. rlhe springs are functioned for the purpose above mentioned when the machine turns a corner, which places a lateral strain upon one or the other end of the chain. rEhe invention is very simple in construction, and can be manufactured and sold at a very nominal cost. i

TWhile it is believed that trom the toregoing description, the nature and advantages ot the invention will be better linderstood, I desire to have it understood that l do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

`What claim is:

An anti-skid attachment for automobile wheels comprising` a chain adapted to eX- tend transversely over the tread ot the tire, branches projecting trom one end ot the chain, sleeve-like members of yieldable material carried by said branches, a short chain ranged at each side of the Wheel, and each spring* having its teiminals secured to the @bain at Spaoed points to provide a Slack in 10 the Chain :it the opposite sides of the Wheel 'for tbe purpose speoied.

n testimony whereof a-HX my signature.

LOUIS C. STUKENBORG.
